REVOLVER.

EJPECIFICATION forming part of Letters Patent No. 339,1flt9, dated April6, 1886.

Application filed February 20, 1886. Serial No. 192,710. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. GILLEY, of Norwich, in the county of NewLondon and State of Connecticut, have invented certain new and usefulImprovements in Fire-Arms.

of which the following, taken in connection and the hammer, thusallowing the pistol to' be used in the usual manner-that is, by pullingthe hammer back by hand and allowing the trigger to engage, thenreleasing the hammer by pulling the triggeralso to be used, when it isdesired to fire rapidly, by drawing the trigger clear back and thenfirmly holding it, while the other hand may be used in drawing back thehammer and allowing it to fall without engaging at all with the trigger,which action can be repeated with great rapidity. These objects I obtainby the mechanism shown in the accompanying drawings, in which-- Figure 1is a sectional view showing the operating parts in elevation. Fig. 2 isan elevation taken from the opposite side from that of Fig. 1, partsbeing broken out to show details. Fig. 3 is a perspective view showingthe trigger and the stop-lever. Figs. 4 and 5 are elevations showingdetails, and Fig. 6 is 2. diagram to represent the action of therevolverlever. A in the drawings represents the stock; C,

.the revolver-chamber; B, the revolver-axle,

and D the hammer. The hammer Dis acted upon by the mainspring D in theusual manner, and has pivoted to its front lower part the revolver-leverK, as indicated at D Fig. 1. The trigger E, Figs. 1 and 3, is pivoted ate, and is acted upon by the spring E. 'This trigger, in addition to itspawl-point Ff, hasa shoulder, E. This shoulder E serves to act upon thepoint H of the stoplever H, the stop-lever H being pivoted at h, and isprovided with a stop-boss, h, (see Figs. 1, 2, and 3,) so that when thetrigger is in a certain positionthat is, when holding the hammer athalf-cock-it, acting through the shoulder E and the point H of thestop-lever H, will release the revolver-cyli nder. The stopiever H hasan upward-projecting arm, H, the upper end of which is so bent that itengages with the projection D (see Fig. 2) on the rear side of thehammer, so that as the hammer is drawn back it, acting through theprojection D and the arm H", will draw the stoplever H out of place andrelease the revolvercylinder C. Thus I have two distinct mechanisms forop erating the stop-lever. hammer is formed in a peculiar manner for apurpose which I will now explain.

In Fig. 1 the pawl-point E is held by a rest ing-point on the hammer D,as shown near the safety-notch d. The safety-notch d is, as usual, quitenear the resting'point, and the half-cock notch d is but a shortdistance from the safety notch d, as shown in Figs. 1, 4, and 5; but itwill be observed that the full-cock notch d is comparatively remote fromthe other notches, so that the hammer has a long sweep in the movingfrom half-cock to full-cookthat is, this movement alone is sufficient,acting through the revolver-lever K, to make atull movement of therevolver chamber. arrangement I can have and maintain therevolver-chamber fastened or locked during the whole movement of thehammer from its firing-point to half-cock, so that there is no danger ofthe revolver'chamber getting out of place during the act ofhalf-cocking. An other advantage of this construction is that themovement of the revolver-lever K through the full swing of the hammerfrom full-cock to the firing-pointwill be more than one notch of therevolver-ratchet. This is illustrated in the diagram, Fig. 6, in whichthe lever K, (indicated by dotted lines,) is in contact with the notch Kwhen the hammer is at full-cock, and is considerably below the nextnotch K, as is indicated by the lever K, (in full lines,) when thehammer is at the firing-point. It is to be observed that the lever Kalways moves when the hammer moves, but it being so much below the notchK the hammer may move from the firing-point to half-cock before the endof the lever K will engage with the notch By this The lower part of theK Thus during the movement of the hammer from the firing-point tohalfeock the revolverchamber may remain locked, and precisely-at thispoint. When the revolver-chamber is released, the revolver-lever K comesinto contact with a notch, thus preventing the revolverchamber frommoving at all in the wrong direction.

I claim 1. In a fire-arm, the combination of the revolver-chamber O,revolver-lever K,its ratchet and hammer D, said hammer having upon'itslower limb a safety-notch, d, half-coclr notch d, and a fu1l-cock notch,d, all soplaced that the hammer may move from the firingpoint' tohalf-cookwithout causing any movement of the revolver-cylinder, and thatthe movement of the hammer from half-cock to full cock will give therevolver-lever K sufficient motion to operate the revolver-chamber, withthe trigger E, having a shoulder, E", and a stop-lever, H, all operatingtogether, substantially as described, and for the purpose set forth.

2. In a fire-arm, the combination of the trigger E, having a shoulder, Eand the stoplever I-I, having an arm, H, with the projection D on therear of the hammer D, all operating together substantially.as described,and for the purpose set forth.
